Usage

To run the Narcissus shell, install the SpiderMonkey shell and either set the NJS_SHELL environment variable to the path to the js executable, or creating a symbolic link to js in the top-level Narcissus directory. Then run Narcissus with the njs script.

                        JS expression to evaluate
